CLEMENT ADJUSTER- S. CLARKE AND RUPERT W. LOWE, OF SHREVEPOR'I,LOUISIANA. GRIP DEVICE FOR PUMPING EQUIPMENT.

Application filed September 17, 1923. Eerial No. 663,267.

States. residing at Shreveport, in the parish of Caddo and State ofLouisiana, have invented certain new and useful Improvements inAdjuster-Grip Devices for Pumping Equipment, of which specification.

This invention relates to means for adju'stabiy the following is aimprovements in connecting walking beams of pumping equipment to thepolish or pump rod.

A further object of this provision of an adjuster invention is the gripdevice for pumping equipment, such as is set forth in our co-pendingapplication Serial Number 604,32%, filed December 1922, and embodying anovel means for adjustably connecting the coupling rod to the polishrod.

A. further object of this provision of novel means fo invention is the rachustably connecting rods or like elements so that the same may bequickly adjusted int ed anti-slip coupled relation.

.0 firmly connect- Other objects and advantages of this invention willbe apparent during the course of the following detailed description.

In the drawings, wherein for the purpose of illustration is shown butthe preferred embodiment of this invention the letter A may generallydesignatev pumping equipment ordinarily utilized in connection with thepumping of oil, which embodies an improved adjuster grip device orcoupling arrangement B.

The pumping equipment A preferably includes the supporting standard 10upon the upper end of which the walking beam 11 is oscillatively mountedintermediate its ends for operation by any approved means 12. The polishor pumping rod 15 is reciprocably mounted within a casing or tube 16ordinarily provided therefor, for pumping of oil or the'like, inaccordance with well known principles. The improved device B is utilizedfor operative connection of the polish or pumping rod 15 to the walkingbeam 11.

Referring to the improved device 13, the same preferably includes anovel coupling or connecting rod 20,-of a single piece of durable metal,preferably being polygonal shaped in cross section, and solid throughoutits length. This rod 20 includes an intermediate straight body portion21; an upper straight portion 22 offset as by a diagonal portion 2 3from the run of the intermediate portion 21; and a lower straightportion 24. relatively shorter than the upper straight portion 22,offset from the intermediate'por tion 21, asby a diagonal portion 25.The upper and lower portions 22 and 24 respectively are offset from thesame side of the intermediate or body portion 21, and are offset atdifferent distances; the upper portion 22 being offset for the greaterdistance. Means is provided upon the upper por tion 22 of the couplingrod 20 for oscillatively connecting the same to the walking beam 11.This means is preferably identical with the construction set forth inour copending application above referred to, and embodies a cross head32' providinga body portion 33 which has a squared or polygonal shapedopening 34 therein for receiving the free squared end 22; the latterhaving shoulders 35 thereon to affix the cross hea 32 in position.Cylindrical shaped trunnions 38 and 39 are preferably integral with thebody 33, as a part of the cross head, extending in opposite directionsand in aligning relation. These trunnions are adapted to rest indepressions provided in a split end of the walking beam 11. as canreadily be seen from Figure 1. of the drawings. Beinforcing ribs may beprovided along the tops of the trunnions3S and 39, extendinglongitudinally thereof. A staple may be carried by the cross head 30, bylateral extensions or wings 4-1, substantially illustrated in Figure 2of the drawings, so that the same may receive a supporting hook or likeelement, as can well be understood by those skilled in the art to whichthis invention relates.

Novel means is provided at the lower end of the coupling rod 20 forclamping the same to the pumping rod 15. This means 50 includes aclamping ring 51 and a wedge member 52. The remotest offset face of thelower portion 24 of the coupling rod 20 is longitudinally grooved inV-shaped manner, as at 53, and within which the pumping rod 15 may fit.The clamping ring 51 is preferably of rectangular formation and of verydurable metal. The clamping wedge 52 is preferably of metal and at oneside 55 thereof is provided with a V-shaped groove 56 extendinglongitudinally thereof. The opposite side 57 of the wedge 52 is disposedin tapered relation with respect to the side 55 in which the groove 56is formed.

Referring to the means of connecting the polish rod or pumping rod 15 tothe coupling rod 20, it is to be noted that the polish rod 15 isdisposed in the groove 53 of the offset end 24 of the coupling rod 20,and when in this relation the axis of the polish rod 15 is in aligningrelation with the offset upper end 22 of the coupling rod 20, so thatthe said axis of the polish rod 15 is in intersecting relation withrespect to the axis on which the coupling rod oscillates, as definedby-the trunnions or bearings 38 and 39. The clamping ring 50 is thenslipped over the offset end 24 of the coupling rod 20 and the pump rod15, to adjacent the juncture of the diagonal portion 25 of the couplingrod 20. The wedge member 52 is then slipped from: the top down throughthe rectangular shaped clamping ring 51, at the opposite side of thepolish rod 15 from where the same abuts the coupling rod 20; the groove56 receiving the polish rod 15. The tapered surface 57 of the wedge 52then abuts an end of the rectangular shaped ring 51, so that uponforcing the clamp 52 downward into the ring, it is apparent that thepolish rod 15 will be securely clamped to the coupling rod 20 infrictional biting relation therewith. Incident to the fact that thegrooves 53 and 56 are V-shaped the sharp edges at the juncture of saidgrooves with the surfaces or sides in which they are formed will biteinto the circular polish rod 15, and in clamping relation therewith willhold the pumping rod 15 and the coupling rod 20 in a firm non-slipadjustment.

From the foregoing description of this invention it is apparent that thenovel means 50 for connecting the pump rod 15 to the coupling rod 20will effectively perform the purpose for which the same is provided. Itassures quick adjustable connection of the pump rod 15 to the couplingrod 20, and when once in clamping relation will hold the pumprod 15against liability of any slipping action whatsoever with respect to thecoupling rod 20. The portions 21, 22 and 21 of the coupling rod 20 areof course in parallel relation; the intermediate portion 21 being thelongest to permit of a considerable adjustment of the pumping rod 15with respect to the coupling rod 20.

Various changes in the shape, size, arran gement of parts may be made tothe form of invention herein shown and described, without departing fromthe spirit of the invention or the scope of the claims.
